Re: [Matplotlib-users] Cannot run basemap examples

[Mike E. <mik...@gm...>]

Hello Jeff,

I tried loading the file etopo20.pickle by itself but got the same error:

import cPickle
a =3D cPickle.load(open('etopo20.pickle','rb'))

Traceback (most recent call last):
  File "<stdin>", line 1, in ?
  File "/usr/lib/python2.3/site-packages/numarray/generic.py", line
159, in Cla\ssicUnpickler
    self.__setstate__(state)
  File "/usr/lib/python2.3/site-packages/numarray/numarraycore.py",
line 463, i\n __setstate__
    self._type      =3D state["_type"]
AttributeError: ("'str' object has no attribute 'name'", <function
ClassicUnpic\kler at 0xb71e48b4>, (<class
'numarray.numarraycore.NumArray'>, {'_type': 'Floa\t32', '_itemsize':
4, '_shape': (1081,), '_bytestride': 4, '_byteoffset': 0, '_\version':
'1.1', '_byteorder': 'big', '_data': <memory at 082ee9a0 with
size:43\24 held by object 082ee980 aliasing object 00000000>,
'_strides': (4,)}))

Looking at etopo20.pickle itself, the 4th line reads
'cnumarray.generic' - I'm guessing that means it is stored using
numarray.
Do I need a specific version of python or numarray to read it? I have
both Numeric (23.1) and numarray installed already.

Mike.

ject.  You can either install Numeric, or I can re-pickle it for you with n=
umarray.
